IMPROVED SUGAR-BOILING APPARATUS.

Specification forming part of Letters Patent No. Q3319! dated August 2, 1854.

. tral and longitudinal section, of the same; Fig.

5, a top view of the furnace as it appears without the sap-pan.

The principal object of my invention is to.

enable a sugar or sap pan containing boiled sap or saccharine juice to be removed from the furnace for heating.

In the drawings, A denotes a firearch or furnace, as used by maple-sugar manufacturers for heating a sap pan or vessel. This furnace I construct with a smoke channel or space, a, extending partially around its fuel-space b, and opening at either or both ends into the same. This smoke-channel also opens into a chimney or discharge-pipe, B. A sap pan or boiler is represented at C, it being a. shallow vessel of sufficient size on its bottom to cover the enti re top of the furnace when placed thereon.

Combined with the furnace and its smokechannel is a bent siphon-tube, 1), whose upper end is placed directly underneath a faucet, 0, extending from a sap-reservoir, E. The said siphon-tube projects downward, and is turned horizontally and caused to pass into the smokechannel and to run along within it, and finally is bent in a reverseddirection and passed out of such channel and carried upward and over, so as to discharge into the sap-pan when the latter may be on the furnace. The purpose of this siphon-tube, so arranged with respect to the furnace, is to enable the liquor discharged into the sap-pan to be more or less heated before its entrance therein. As p art of the siphon extends within the smokechannel, such part will be subjected to theheat of the smoke thereof, and of course will heat the liquor more or less while it may be passing through it.

The machinery for removing the sap-pan I from the furnace consists not only of a railway and a mechanism for elevating it, but of a carriage (to sustain the sap-pan and run on the railway) and machinery for moving the said carriage on the railway, the whole-being as hereinafter explained.

In the drawings, G denotes the railway, which consists of areetangular frame, whose longitudinal timbers d d are grooved on their.

upper surfaces, as shown at c c. This railway rests on four cams, f f f f, carried by two hori zontal shafts, g g, which extend transversely underneath the railway, and have their journals supported in bearings projecting from stationary beams h h, or parts of a frame erected over the sap-pan. There is a crank, t, pro jecting from one end of each of the shafts g 9. These cranks are connected to the shorter arm of a lever, 75, by means of two rods, H, which are jointed to the lever and the wrists of the cranks. A carriage,'H, having four hooked rods or hangers, m m m m, to hook into eyes a; x as m at the four corners of the sap-pan,

suspended from it, has four wheels, at a a a, to rest and run in the parallel grooves e c of the railway. There are two ropes, o p, affixed to this carriage, and extended from it in opposite directions. The rope 0 goes around two leading sheaves, q 1", arranged as shown in Fig. 1, and thence downward to the barrel of a wind lass, 8. Furthermore, the rope goes around a leading sheave, t, and thence down to the said Windlass, the two ropes being wound around the Windlass-barrel in opposite directions, and eachrope being fastened to it. By laying hold of a crank, a, fixed on the shaft of such Windlass-barrel and turning the Windlass thereby, the carriage H will be moved in either direction on its railway. So, by moving the lever 70, the railway may be either raised or lowered.

WVhen the sap-pan'is on the furnace, and it may be desirable to transfer such 'pan therefrom and to a pair of supporting-horses v o, the carriage should be moved directly over such sap-pan, and the suspension-rods should be hooked to the pan. This having been done, the lever 70 should be moved so as to cause the railway and the carriage to be forced upward, and in a manner to lift the sap-pan off the furnace, after which, by revolving the crank of the windlass, the. carriage may be moved on its railway so as to remove the pan from the furnace to the horses, upon which it may be lowered by turning the lever 70, so as to lower the railway.

I would remark that when the saccharine cong i r 43,701

tents of a sap-pan may have been sufficiently boiled for being crystallized, it becomes desirable to remove them speedily from the action of the fire, otherwise they may become injured thereby. With my machinery this can be accomplished to great advantage.

I claim- .1. The combination for raising the sap-pan off the furnace and transferring it to horses or supporters near the same, the said combination consisting not only of the carriage H, with its hangers or suspension-rods m m m m, the movable railway G, and the mechanism-that s, the lever is, the connecting-rods Z Z, the

cranksi i, the shafts g g, and the eamsfffffor raising; the latter and the carriage, but of mechanism-viz., the Windlass s and the'ropes 0 p-f0r moving the carriage along on the railway, as specified.

2. The combination of the siphon supplytube with the furnace A, substantially in manner and so as to operate with it the reservoir and sap-pan, as specified.
